This document describes a Chinese stock screen using daily price movement and convertible bond information. It selects stocks with an amplitude above 1, a nonempty name for outstanding convertible debt, and a daily return between negative 5% and positive…
This document proposes a daily pre-open stock screen centered on MACD being above the zero line, then ranks qualifying names by a measure of individual-stock attention. It also includes a listing-age filter, described as favoring companies that have been…

This document describes a Chinese equity screen that looks for stocks with turnover between 3% and 12%, a reversal pattern, and at least one limit-up event during the prior month. Its stated rationale is to identify recently popular stocks while using…
This article introduces Granger causality and transfer entropy as ways to study directional predictive relationships in time series. Granger causality tests whether a source series improves forecasts of a target beyond the target’s own history, commonly…
This Chinese-language forum post asks how to import tick data into vn.py for backtesting when the graphical import interface appears to support only minute-level or coarser data. The author considers loading records into the database with custom code and…
